Background: A set of hardware stereotactic radiosurgery is designed and constructed. The scope of this article is to describe how we have designed and developed stereotactic collimation assembly for a 9 MV Neptun 10 PC linac. Materials and methods: One collimator holder and six collimators were made, with their radiation field diameter between 12.5 mm to 25 mm at isocenter level. Beam data, suc...
The presented paper deals with the use of physical modelling to study degassing process aluminium melts in refining ladle by blowing inert gas through a rotating impeller. For purposes modelling, plexiglass model scale 1:1 is used for operating ladle. Part hollow shaft supply that equipped an impeller and two baffles. melt simulated at decrease dissolved oxygen liquid (water). This aimed evalua...
The Volume Slicing Display is a device enabling the interactive exploration of volumetric data (e.g. medical images) using a piece of Plexiglass or paper that functions both as a control interface and as a passive, untethered projection screen. With the VSD, radiologists would be able to retrieve a certain amount of three-dimensionality from a flat X-ray plate at any time, by just touching cert...
The velocity fields along a selfvibrating physical model of vocal folds were studied experimentally. The shape of the vocal folds was specified according to data measured on excised human larynges in phonation position. The model was fabricated in 1:4 scale as a silicone body vibrating in the wall of a plexiglass wind tunnel. The model is not excited externally and oscillates only due to coupli...
The vibrofluidized bed developed in this work, consisting of a transparent plexiglass tube with an inner diameter of 0.1 m and a height of 0.5 m, was designed for the fluidization of adipic acid. The fluidization behavior of dry adipic acid with particle diameters in the range of 75 600 μm and a density of 1340kg/m was studied using mechanical vibration for different sample loads. Variables stu...
Dual-energy mammographic imaging experimental tests have been performed using a compact dichromatic imaging system based on a conventional x-ray tube, a mosaic crystal, and a 384-strip silicon detector equipped with full-custom electronics with single photon counting capability. For simulating mammal tissue, a three-component phantom, made of Plexiglass, polyethylene, and water, has been used. ...
Reconstruction of Rayleigh-Lamb dispersion spectrum based on noise obtained from an air-jet forcing.
The time-domain cross correlation of incoherent and random noise recorded by a series of passive sensors contains the impulse response of the medium between these sensors. By using noise generated by a can of compressed air sprayed on the surface of a plexiglass plate, we are able to reconstruct not only the time of flight but the whole wave forms between the sensors. From the reconstruction of...
Horizontal hydraulic transport of ice particles suspended in water which is used in cooling systems has several advantages, such as its friendliness to the environment and its relatively low operation and maintenance costs. In this study, as a first approximation one dimensional model is developed. Simulation model calculates the pressure drop of the flow of solid-water two-phase mixture inside...
This paper is concerned with experimental results of sand avalanches flowing down inclined plexiglass chutes with lateral confinement. Specifically we introduce the particle image velocimetry (PIV) technique for granular avalanches. We discuss the differences and problems in comparison with “usual” PIV. After this, we present surface and side velocity measurements that are obtained at different...
We report on experimental studies of spatio-temporally heterogeneous stickslip motions in the sliding friction between a hard polymethyl methacrylate (PMMA, plexiglass) block and a soft poly-dimethyl siloxane (PDMS, silicone) gel plate. We perform experiments on two PDMS gels with different viscoelastic properties. For the less viscous gel, large and rapid events are preceded by an alternation ...
